To all whomvlt may concern: ln the drawings above 'briefly described,

especially when the ground is very rough or full of stumps, the entire machine is preferably knocked down and carried to the destination, and then again set up for use, but

otherwise the wheels 17 and 1S may be used` when moving the machine from one location to another.

A pair of vertically elongated runways 22 are detachably connected by clamps or the like 23 to the longitudinal beam 2, and slides 24, preferably having antifriction rollers 25, are movable vertically along said runways, said slides having downwardly opening saw-guides 26 which slidably receive a cross out saw 27 which may be of any desired form. A comparatively light saw, however, is preferably employed in order that it may be morey easily operated. Attention may here be directed to the fact that the clamps 23 are of downwardly-opening, hook-shaped formation, `so that it is simply necessary to hook them over the beam 2, set screws 23:l being threaded `through said clamps so that they may be held in place after they have been adjusted to the proper position along the beam. To detach the clamps and the guideways 22 carried thereby, when the entire machine is disassembled to be moved from one place to another rather remote point, it is simply necessary to loosen the set screws 23a and unhook the clamps 23 from the beam 2. Cables 28 rise from the slides 24, are trained over sheaves 29 at the upper ends of the runways 22, and are connected to a manually rotatable drum 30 which is suitably mounted between the standards 6y andl 7. Any suitable means, such as a pin 31 may be employed for holding the drum 30 normally against rotation, but whenever desired, this pin may be removed so that the weight of the slides 24 and the guides 26 will act to feed the saw 27 downwardly. l prefer to employ some suitable brake, such as a strap 32 and a hand lever 33 for controlling the rotation of the drum 30 in a direction to permit unwinding of the cables 28 and it will therefore be seen that the amount of downward pressure exerted on the saw 27 by the slides 24 and the guides 26, may be readily controlled. The lever 33 is preferably mounted on the bar 3 adjacent the operators chair 10 so that it may be readily controlled.

Attention may here be directed to the fact that by the provision of the drum 30 and the cables 23,`the saw guides may be raised and loweredas desired, independently of the carriages 34 which' may be adjusted vertically along vthe end frames 1. In my pre'- vious patent, the corresponding slides and carriages could be adjusted4 onlyf'in unison and this was found tobe a great handicap in the proper operation of the machine. Attention is also directed` to the 'fact that whereas in my patented machine, l employed a pair of segments on the carriages v on the wheels 35 so that slack may be removed from Vsaid cables` whenever necessary. The drums 39 are provided with suitable means 40 for locking them againstiretrograde motion after they have once been adjusted properly. The cables 37 travel in the peripheral grooves 36 and the operating cables 41 for the wheels 35 are also received in said grooves. rlhe cables 41 pass oppositely around a segment 42 which is rigidly carried by the drive shaft 14 between the standards 6 and 7. The segment-42 is'provided with suitable peripheral grooves to receive the cables 41 and is also equipped with a drum 43 to which said cables are secured so that they may be. tightened as required. Appropriate guides 44 are carried by the segment 42 for the cables 41 and any desired locking means may be employed for the drum 43. y i

For vertically adjusting the carriages 34 as required, cables 45 extend upwardly from said carriages over suitable guides 46 at the upper ends of the frames 1, said cables being wound around adrum 47 which is rotatably mounted between the standards 6v and 7 above the drum 30. Drum 47 may be equipped with any suitable means for holding it in adjusted position. y

As disclosing the preferred form of foot treadle, reference may be made more particularly to Figs. 2, 4 and 7. pair of wheels 48 are rigidly secured upon the drive shaft 14 and are provided with peripheral teeth`49 with which the ends of an upper foot bar 50 and a lower foot bar 51 are adjustably engaged. The bars 50 and 51 may be adjusted along the peripheries of the wheels 48 until the most advantageous and convenient relation vis obtained, and although said bars could then be locked in position by any preferred means, l have shown wedges 52 for this purpose, said wedges being driven into openings 53'in radial arms 54 which carry the bars 50 ,and
